Abstract

Radar communication systems are needed to predict weather and other military needs. One of the important parameters required for a radar communication system is an antenna with high performance and broad bandwidth that can improve the resolution. The research proposes a single patch microstrip antenna that is rectangular and has a 8 GHz resonance frequency for radar applications that have high bandwidth and performance. The antenna was developed with two dual feed lines connected to the peradiation element with the 2x1 element array technique aimed at increasing the bandwidth of the frequency. The antenna is designed using a FR-4 substrate with a tangent loss of 0.0265, a dielectric constant ( |r) = 4.3, a substrat thickness (h) = 1.6 mm. The dimensions of the rectangular single patch microstrip antenna substrata are 20x20 mm2 and 35x35 mm2 for the dual feed line antenna design. Simulation results from the antenna development showed a 159.62% increase in bandwidth compared to the original antenna design. The reflection coefficient also increased from the original design antenna, which was -16.36 dB, to -25.64 dB or an increase of 56.72%. This antenna is very suitable and recommended to be applied as a receiver antenna on radar communications systems

Abstract

Sistem komunikasi 5G membutuhkan antena sebagai perangkat penerima yang memiliki kinerja tinggi termasuk bandwidth yang lebar dan gain yang tinggi. Antena mikrostrip mempunyai kelebihan seperti biaya yang murah, cocok untuk frekuensi tinggi dan mudah diintegrasikan dengan perangkat lain. Salah satu kelemahan antena mikrostrip adalah gain yang rendah. Oleh karena itu, antena mikrostrip dengan gain tinggi sangat dibutuhkan untuk mendukung sistem komunikasi 5G. Penelitian ini memberikan solusi dengan mengusulkan antena mikrostrip dengan gain tinggi yang beroperasi pada frekuensi resonansi 3,5 GHz untuk sistem komunikasi 5G. Antena usulan dikembangkan dalam lima tahap dimulai dari satu elemen, susunan seri dua elemen, susunan seri 4 elemen, susunan seri 8 elemen dan susunan seri plannar 8x2 elemen. Teknik susunan seri plannar dan menggunakan spiral stub pada line feed serta slit diusulkan untuk meningkatkan gain antena mikrostrip. Dalam tulisan ini, simulasi dan pengukuran dari antena usulan ditampilkan dan dibandingkan secara komprehensif untuk menunjukkan peningkatan kinerja dari setiap tahap pengembangan model usulan. Berdasarkan hasil pengukuran, antena yang dirancang memiliki gain maksimum sebesar 13,08 dB pada frekuensi resonansi 3,5 GHz. Gain antena masing-masing meningkat 118 % dibandingkan dengan antena elemen tunggal. Oleh karena itu, antena usulan ini dapat direkomendasikan untuk digunakan sebagai antena penerima sistem komunikasi 5G
